All of my Blue Niko Hydragenas look dead......where there is always new growth on old wood the buds were frozen. The plants are not dead as there are leaves at the very bottom beginning to show. Do I go ahead and cut the old wood stems down to the ground and start again? These are all very well established plants that are big....there is no growth on any of the old growth branches. Thx
Hydrangeas were hit pretty hard by our cold winter. You can scratch the branches with your fingernail and look for green tissue. If you see it, the branch is still viable. Be patient and wait for new growth. Once the plant starts actively growing you will have a better idea of what to prune. Only prune brown dead wood.
